Quad 2-Channel Multiplexer
The TC74VHC157 is an advanced high speed CMOS QUAD 2CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissipation.
It consists of four 2-input digital multiplexers with common select and strobe inputs.
When the STROBE input is held “H” level, selection of data is inhibited and all the outputs become “L” level.
The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs.
An Input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
Features
High speed: tpd = 4.1 ns (typ.) at VCC = 5 V Low power dissipation: ICC = 4 μA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Power down protection is provided on all inputs. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 V to 5.5 V Low noise: VOLP = 0.8 V (max) Pin and function compatible with 74ALS157
